Ivory moire sheath and coat suit

Because of the (removable) shoulder pads, I think this set is from the mid 80's. It belonged to my friends late sister. The color is more an ivory than beige. It's a moire pattern. The sheath is a size 14. bust is 40-42". Length from the back down is 32" The sleeves on the unlined coat are 24" long and it's 35" long from the back collar to hem. Both the dress and long jacket can be worn separately (see photo).It's 63% Rayon 37% Acetate but looks like raw silk. Very Jackie O chic.
